Piconet vs Scatternet-Difference between Piconet and Scatternet
This page compares piconet vs scatternet concept used in bluetooth and mentions difference between piconet and scatternet bluetooth network types.
It is a basic unit of bluetooth networking. Devices function as master and slave in piconet. There are two configurations viz. one master and one slave or one master and multiple slaves. Master will determine channel and phase. Figure-1 depicts bluetooth piconet structure.
As piconet will have 3 bits. This means piconet can have maximum 8 devices. This includes 1 master and 7 slave bluetooth devices.
The bluetooth network consisting of one or more piconets is known as scatternet. The devices in one piconet type may function as master or slave in another piconet type of the same scatternet. This bluetooth network type allows many devices to share the same network area. This will allow efficient use of the bandwidth. Figure-2 depicts bluetooth scatternet structure.
As scatternet is interconnection of multiple piconets, it can accommodate more than 8 devices.
